# Setup make rules for creating a zip archive.
#
# Parameter 1 is the name of the rule. This name is used as variable prefix,
# and the targets generated are listed in a variable by that name.
#
# Remaining parameters are named arguments. These include:
#   SRC
#   ZIP
#   INCLUDES
#   INCLUDE_FILES
#   EXCLUDES
#   EXCLUDE_FILES
#   EXCLUDE_PATTERNS - Patterns with at most one % wildcard matching filenames
#                      and not directories.
#   EXCLUDE_PATTERNS_$dir - Exclude patterns just like above but specific to one
#                           src dir
#   SUFFIXES
#   EXTRA_DEPS
#   FOLLOW_SYMLINKS - Set to explicitly follow symlinks. Affects performance of
#                     finding files.
#   ZIP_OPTIONS extra options to pass to zip
#   REPRODUCIBLE set to false to disable the step that makes zip reproducible
